The COR is a variable speed, brushless, DC-driven centrifugal water pump designed specifically for aquariums to be intelligent, energy-efficient, unbelievably quiet, and incredibly powerful for its size. The COR includes many quality of life improvements and safety features over a standard return pump: Obstruction detection notifies you of any blockages. Temperature monitoring slows the pump when temperatures reach unsafe levels while still circulating your aquarium and giving you time to address the issue. IQ-Level software (available in Apex Fusion cloud service when connected to an Apex system) allows you to set minimum and maximum flow levels - in the event of a power outage, the COR will remember these levels and never pump water beyond the capability of your overflow or drain.
